Grafted pear trees bear fruit for several years

The fruit of pear is edible and has high nutritional and medicinal value. The cultivated area and yield of pear in China are second only to apple. Anhui and Hebei provinces are concentrated producing areas of pears in China, accounting for about half of the cultivated area and 80% of the output, of which Dangshan County, Anhui Province accounts for about 1% of China's annual output. So, how many years does the grafted pear tree bear fruit?

First, how many years does the grafted pear tree bear fruit?

Grafted pear trees usually bear fruit in about 4-6 years. Due to the variety of pear varieties and different grafting methods, the fruiting time may be different. Grafted pear trees usually bear fruit in about 4-6 years. Due to the variety of pear varieties and different grafting methods, the fruiting time may be different.

2. Grafting methods of pear trees

There are many methods of pear grafting, including split grafting, insertion grafting, ventral grafting and grafting.

1. Split-joint method

Split grafting is carried out on branches with a diameter of 5-6 cm. Now cut the rootstock horizontally to form a smooth cambium, then split it vertically with a grafting knife, cut the lower end of the cuttings into a 2-3 cm long wedge, insert the cuttings into the rootstock and tie them up with plastic film.

two。 Plug-in method

First cut off the cambium of the rootstock with a knife, and then cut the scion into a horseshoe shape (2/3 of the skin on the back of the horseshoe shape). Then insert the previously cut scion into the rootstock, and finally seal it with plastic film.

3. Abdominal connection method

The best period of abdominal grafting is from mid-September to mid-October. In the bald part of the pear tree, some branches were grafted by the abdominal grafting method to form a certain branch group to fill the space and increase the fruiting part.

4. Grafting method:

The method of grafting with a branch of one or more buds as a scion is called branch grafting. According to the different joining methods, it can be divided into splicing, splitting and abdominal grafting, etc.

5. Splice

The scion should have 2-3 full buds. Cut a straight slope of 3 cm long at the lower end of the scion and a 1 cm slope on the back of the scion. Cut the rootstock 3-5 cm from the ground, choose a flat and smooth side, and cut straight inward and downward. It is preferable that the length and width of the incision is similar to that of the scion. Cut the long side inward and the short side out, and insert it into the rootstock cut. In the upper part of the rootstock, the scion shows 2-3 mm cutting surface, the cambium of the rootstock and ear is aligned at least on one side, and then tightly wrapped with plastic strip.

In general, pear trees that do not choose varieties with the same parent should be adapted to local conditions and excellent varieties suitable for local and strong growth should be selected.
